Make Team Calendars display in a Confluence Page Gadget, for use on a JIRA Dashboard

When using a gadget for pie chart in Dashboards, if the field has more than 1 context and the filter is based on this custom field it turns out that this will show two different rows with information of each context but without specify which one is based in what context.

One row is related to the context that will show all projects and the other one is to show the specific information on the field.

It is needed that for this kind of dashboard information this can be a idea box informing which one is from what context.
